Abstract
Abstract Each section of telescoping pipe is supported by a hanger depending from a straight, horizontal, elevated, transverse beam. The beam is mounted for traverse travel on overhead structures. A special suction head is carried by a carriage and connected to the last of the telescoping sections. A pick-up pipe depends from the special suction head. The structural support of the suction pipe is separated from the air seals therein. When the pipe is angled forward, an electric motor upon the carriage drives a pneumatic tire pushing against the beam to extend the telescoping sections. When the pick-up pipe angles back, the electric motor is driven in the opposite or reverse direction to retract the sections of pipe.
